Blog Post: TheAlephBlog: Yahoo Finance News

May 11, 2012 by MoneyScience   Comments (0)

I want to call attention to News at Yahoo Finance.  I have used Yahoo Finance for 15 years and have found it valuable.  As time has gone on, Yahoo has added low value news sources like Seeking Alpha, Motley Fool, and Zacks.  These are websites that if I could eliminate them, it would be done already.read more...

Blog Post: Falkenblog: Asness and Frazzini Make Simple Point on Value

May 11, 2012 by MoneyScience   Comments (0)

Cliff Asness has been thinking, writing, and investing on value and momentum ideas since the late 1990's, and as the head of a successful hedge fund, it's fair to say he's one of the world's foremost experts on these equity factors. He and Andrea Frazzini recently put up a The Devil in HML's Details on the SSRN, so this is all new to me even though it has been around for a year elsewhere (strangely, there are more downloads than abstract views). Here's the finding. Value, as...

Published / Preprint: Optimal retirement consumption with a stochastic force of mortality. (arXiv:1205.2295v1 [q-fin.RM])

May 11, 2012 by MoneyScience   Comments (0)

We extend the lifecycle model (LCM) of consumption over a random horizon (a.k.a. the Yaari model) to a world in which (i.) the force of mortality obeys a diffusion process as opposed to being deterministic, and (ii.) a consumer can adapt their consumption strategy to new information about their mortality rate (a.k.a. health status) as it becomes available. In particular, we derive the optimal consumption rate and focus on the impact of mortality rate uncertainty vs. simple lifetime uncertainty...

Published / Preprint: Electricity price modeling and asset valuation: a multi-fuel structural approach. (arXiv:1205.2299v1 [q-fin.PR])

May 11, 2012 by MoneyScience   Comments (0)

We introduce a new and highly tractable structural model for spot and derivative prices in electricity markets. Using a stochastic model of the bid stack, we translate the demand for power and the prices of generating fuels into electricity spot prices. The stack structure allows for a range of generator efficiencies per fuel type and for the possibility of future changes in the merit order of the fuels. The derived spot price process captures important stylized facts of historical electricity...

Published / Preprint: The Valuation of Clean Spread Options: Linking Electricity, Emissions and Fuels. (arXiv:1205.2302v1 [q-fin.PR])

May 11, 2012 by MoneyScience   Comments (0)

The purpose of the paper is to present a new pricing method for clean spread options, and to illustrate its main features on a set of numerical examples produced by a dedicated computer code. The novelty of the approach is embedded in the use of structural models as opposed to reduced-form models which fail to capture properly the fundamental dependencies between the economic factors entering the production process.
